This is a wonderful thread. I was just looking at Stuart Varden’s great web site, Nostalgia: Honoring Fats Navarro http://csis.pace.edu/~varden/navarro/navarro.html
Engraved on Fats' tombstone is is well known quote- "I'd like to play a perfect melody of my own, all the chord progressions right, the melody original and fresh - my own." - which seems to me to sum up the swing-to-bop -- bop ethos.
And, speaking of Fats, let’s not forget the wonderful young Ernie Henry and Allen Eager– I don’t think they made any leader dates in the 40’s (maybe Eager did a couple of 78s for Savoy and Jade), but they were indispensable presences in the classic Tadd/ Fats bands.
